The US Court of International Trade blocked U.S. President Donald Trump's tariffs, saying he 'overstepped his authority'.On April 2, a day he described as 'Liberation Day', Trump invoked an emergency law to impose unilateral tariffs on nearly every country.He claims his use of the emergency measure was justified because he was responding to a national emergency. But the court rules that as per the U.S. Constitution, Congress can regulate trade with other countries, and the president does not have superseding powers over it.The Trump administration filed an appeal almost immediately, which in practice means a legal battle must follow before it is decided whether the tariffs can go ahead.Meanwhile, Wall Street critics of Trump have accused him of always 'chickening out', since the tariffs have been mostly halted anyway. When asked to respond to this accusation by a journalist, Trump said it was "a nasty question".
